FAQ
Why does generation fail for some formats?
Each format has strict charset/length rules. For example, EAN/UPC usually requires fixed-length numeric input.
How can I improve print clarity?
Use higher export scale (2x/3x), and increase bar width or margins when needed.
When should I use SVG instead of PNG?
Use SVG for lossless scaling, print layouts, and post-editing in design tools.
